How do I change a CSS bakground on refresh?

I have a drupal site located at http://www.claudebing.com and I want to be able for the background image on the front page to change when refreshed. I have 10 or so images that are all the same size in my gallery, http://gallery.claudebing.com under the album Backgrounds (rotating). Is there a way to call a php script in the CSS file that will randomly select an image from that album? Or would it be simpler to call a file from a directory?
